For the filling and onions
3 ½ ozHazelnuts
11 ozBroccoli
½ tspSalt (0.11 oz)
4 Onions
1 tbspOlive oil (0.47 oz)
ozBrown sugar
100 mlWhite wine
100 mlVegetable broth
Seasoning for the filling
½ Lemon
1 tbsp, groundTarragon
1 dashSalt (0.01 oz)
½ tsp, groundBlack pepper


  • hand-held blender / immersion blender or blender
  • grater
  • skillet (frying pan)
  • citrus juicer (lemon squeezer)
  • saucepan
  • oven
  • casserole dish (baking dish)
  • melon baller

Type of preparation

  • cook
  • chop or grind
  • sauté
  • caramelize
  • squeeze
  • dry roast
  • purée
  • remove the skin
  • grate (shred)


  1. For the filling
    Place the shelled hazelnuts on a baking sheet and roast in a preheated convection oven at 180 °C for 15 minutes. Let cool and then transfer to a plastic bag and roll the hazelnuts firmly until the skin falls off. Chop the hazelnuts and set to the side.

  2. Separate the broccoli florets into larger sections and steam in well-salted water for about 15 minutes, until al dente. In the meantime, continue with the following preparation steps.

  3. Peel the onions and cut off a cap (about one-fourth of each onion). Remove the caps. Use the melon baller to carefully scoop out each onion, leaving the outer two layers intact. Set these onions to the side until step 7.

  4. If you don’t have a melon baller, you can use a small knife to carefully scoop out the onions.

  5. Finely chop the contents of the onions and sauté in a skillet with olive oil until translucent. Increase the temperature briefly and add the brown sugar and stir until the onions caramelize. Set the skillet to the side.

  6. For the onions
    Cut off a thin slice from the bottom of the onions so that they can stand upright.

  7. Bring the white wine and vegetable broth to a boil in a saucepan. Place the onions with their caps in the saucepan and simmer on low heat for about 25 minutes or until they are al dente.

  8. Make sure that the onions are packed in close together in the saucepan so that they don’t tip over. The liquid shouldn’t come up higher than the middle of the onions.

  9. Next steps and seasoning the filling
    In the meantime, combine the finely chopped onions with the broccoli and then coarsely purée the mixture.

  10. Finely grate the lemon peel using a kitchen grater and squeeze the lemons in a citrus juicer.

  11. Add the lemon peel and juice, hazelnuts, and tarragon to the broccoli and onion mixture. Season with salt and pepper, and if the mixture is on the dry side, stir in a little olive oil.

  12. Fill the prepared onions with the broccoli and onion mixture and serve the “Cebollas rellenas” while they are still warm.

Notes about recipe

Hazelnuts: For this recipe, you can either buy shelled hazelnuts or you can shell them yourself.

Types of sugar: The original recipe calls for cane sugar, which is often confused with other types of sugar. Cane sugar is another name for household sugar and is obtained from sugarcane. It can be white or brown. In contrast, raw cane sugar and brown sugar are semiprocessed sugarcane products that contain some residual molasses. This is why they have a brown color.


Larger onions for this recipe: The author uses medium-size onions for this recipe. If you don’t have a melon baller or it is the first time you’ve made this recipe, it will be easier to scoop out the onions if they are larger.

Alternate preparation

A knife instead of a melon baller: Instead of a melon baller, you can also use a knife, but this does require that you have a steady hand.

Herbs and spices: If you like, you can also use additional herbs and adjust the amount of salt and pepper to meet your personal preferences, or even add a little Cayenne pepper.
